RAILWAY-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 773,098, dated October 25, 1904.

Application filed March 19, 1904.

To all whom it may concern: I

Be it known that 1, ANDREW J. PARK, a citizen of the United States, residing at Bokchito, in the Choctaw Nation,-Indian Territory, have. invented new and useful Improvements in Railway-Signals, of which the following is a specification.

This invention relates particularly to railway-signals used in connection with a switch to indicate whether the switch is open 'or closed. I

It is the object of the invention to provide animproved device of the kind characterized particularly by the fact that it willshow both day and night signals in both directions. Other advantages will be apparent with respect to the construction and manner ofoperating' the signal arms or targets and with respect tothe manner of locking the switchlever. 1 r

In the accompanying drawings, Figures 1 and 2 are side elevations of the stand in different positions. Fig. 3'is a rear elevation.

Referring specifically to the drawings, 6 indicates a standard supported upon a suitable base 7. This standard is forked at the top, asat 8, and by means of a bracket 9, fixed to the standard between the forks, carries a lamp 10, which exhibits a white light inboth directions.

Two targets 11 are provided one on each side of the stand, and the arms 11 are pivotedat 12 to the forks 8 to swing vertically.

The target-arms 11 carry the colored-glass or night signals 13-, these glasses being held in screens or frames 14, attached to and depending from said target-arms and so positioned that when the arms are lifted the glasses 18 will be brought in line with the lamp 10 to exhibit a red or other colored light. Obviously the color of the lights exhibited may be varied as desired.

Beyond and behind the forks of the standard the arms 11 are bent toward each other, as at 11 to give a convenient connection to the upper end of a connecting-rod 15, which is connected at its lower end to an arm 16, projecting from the rock-shaft 17 ,which finds its bearings in a pair of bars 18, secured at their front ends to the base 7 and at their Serial No. 198,963. lNo model.)

rear ends to a base 7. Each base is arranged to be spiked or otherwise fastened to the switch-platform or cross-ties.

The rock-shaft 17- has a crank 19 at one end for connection to a switch-rod 20, and at the other end has an arm 21, to which the switch hand-lever 22 is bolted. Another switch-rod,

as shown at 23, may be connected to the arm 21, if desired.

' To hold the switch-signal as set, latches are provided which engage the hand-lever referred to. Each latch consists of a bar 24:, which is hinged at 25 to the base of the stand and has at the topan offset portion 26, having a slot'27, through which the lever 22 extends. These latches are disposed on opposite sides of the lever in the plane of its movement, and

as the lever is swung back and forth it works through the slots at the ends of the bars. The construction is such that when the lever is upright and the signal at safety the offset portions of the latch-bars meet, as shown in Fig. 2. When the lever' is thrown back and down to set the signal at danger, the front latch slides down on the lever and the rear latch slides upon the same. The lever has two projections 28 and 29, arranged on opposite edges to engage the respective latches in the two positions of the signal. At safety when the lever is upright the rear latch 24 engages at its slot und'erthe projection 28, and hence the levercannot be thrown back without manually disengaging the latch from the said projection. When the lever is swung back and down to danger position, the pro' jection 29 is engaged at the slot of the front latch 24 and the lever is prevented from lifting and the targets from falling until said latch has also been manually disengaged from said projection. In practical use a knock of the foot will be found suflicient to effect the disengagement. Y

The targets operate as a day-signal in an obvious manner. As a night-signal the screens carrying the colored glass swing up in front of the lantern on both sides, forming an efli: cient night-signal visible fromboth directions.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination of a signal standard having at the top a lamp showing both ways, and a pair of target-arms pivoted to the standard and connected together and having colorscreens arranged to swing simultaneously in front of the lamp on both sides.

2. The combination of a signal-standard, a lamp showing both ways at the top thereof, a pair of arms'pivoted to the standard and connected together and arranged to swing similarly on both sides of the lamp, day-targets carried at the outer ends of the arms, and night eolor-screens carried by the arms and located to swing in front of the lamp on both sides.

3. The combination of the switch-lever, and the signal connected thereto and operated thereby, of the swinging latch-bars pivoted at the bottom on opposite sides of the lever, 1

and having means at the top to engage the lever in the safe and danger positions respectively.

at. The combination of the lever, and the signal device connected to and operated thereby, of the swinging latch-bars pivoted at the bottom on opposite sides of the lever and having slots at the top through which the lever works, and projections on the lever arranged to engage the respective bars at the slots.

In testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.
